Abstract Large carnivores such as leopards ( Panthera pardus ) experience continuing threats from habitat loss and fragmentation, depletion of prey populations, retaliatory killing following conflicts with humans. We aimed to identify factors affecting leopard occupancy temporal overlap between tigers P. tigris ), their major prey, human activities in the Parsa‐Koshi Complex (PKC), Nepal. deployed 154 cameras for 21 days each along wildlife trails throughout PKC during December 2022–March 2023. found low (0.17 ± 0.04) PKC, greater rates within protected areas, particularly Parsa National Park its buffer zone. Human (63.10 23) livestock (36.46 102) detections were higher across PKC. Leopard was positively associated presence prey. Temporal moderately high tigers, well Our research suggests that coexistence is likely largely facilitated by availability, which may reduce competition. Further, we demonstrate maintaining forest cohesion can improve leopards. Intensifying use agricultural areas could fragmentation increase overall, turn reducing depredation improving leopard‐human co‐existence conservation.
